My brother in law bought a Go kart and needs to know how to know how to put a brake system on it :O
there is no lubricant on the market that can penetrate metal as they claim.
I was told by an AMSOIL dealer to Never Never add anything to your engine oil cause the oil is designed to work on its own so if you put an additive with it , it will no longer do its job as engine oil
this is susposed to be a friction reducer the only way is to find out how many oil microns are present in plain oil and oil with the z max myself i dont think there is an advantage a good motor oil straight thirty straight fourty from a good dealer pens oil or valvoline by itself is a good lubricant at all temperatures. i used to use stp but the only advantage were in my mind i was at the mercy of the advertizers judge for yourself ok.
can buy a disc brake system as a kit. can find one by doing an on line search.
